Dikembe Mutombo undergoing treatment for brain tumor

Basketball Hall of Famer Dikembe Mutombo is undergoing treatment in Atlanta for a brain tumor, the NBA announced Saturday.

Mutombo has been one of the NBA's global ambassadors for years, and recently appeared at Hall of Fame enshrinement events in Springfield, Massachusetts and a pair of preseason games in Saitama, Japan.

He also appeared with U.S. Secretary of State Antony Blinken at an event in the Congo, Mutombo's native country, in August.

“He is receiving the best care possible from a collaborative team of specialists in Atlanta and is in great spirits as he begins treatment," Mutombo's family said in a statement distributed by the NBA. “Dikembe and his family ask for privacy during this time so they can focus on his care. They are grateful for your prayers and good wishes."
